Just installed it on my jalebi and facing some fc like bluetooth has stopped and phone system has stopped on every Boot but they r not affecting the overall usage of the phone(just choose wait and u r good to go)

The rom is a bit laggy but overall good in usage

Some of the colt interiors like network meter in status bar is not working

Here I am requesting u to use round icons by Google and plz include pixel launcher in next build @theHari08

How is the battery backup and what about the camera app
Is it google camera or snap cam???
It has google camera can't tell about battery backup bcs I have just flashed it

few things which are not working are-
status bar customizations such as clock, battery customizations
face unlock/trusted face
privacy guard/advanced app ops
double tap to sleep on status bar or lockscreen to sleep
few app and many settings crashes
cpu freq always clocked to max causing battery drain
also oreo features like PiP and notification dots are not working

but overall good ROM for a beta version
